As far as Pandora is concerned can you use app in Uconnect but use your cell phone's data plan?

According to the Uconnect website:

Bring your entertainment along for the ride with Uconnect® Access+ via Mobile. Stay connected to your favorite music, news and information, with in-vehicle apps like Pandora® and Aha™.
Via Mobile makes it easy to enjoy your favorite entertainment and stay focused on driving. It uses your smartphone's data plan to access Uconnect® System-enabled apps, which you control with your touchscreen, radio or steering wheel controls.
